  1. SC Links IntegrationPoint 7 S. Weisz, J. P. Corso and A. Ballarino

  2. Overview of Point 7 DFBA actual position DFBA actual position IP7 SC links DFH HL-LHC positions

  3. Assumptions retained for the SC link at Point 7 Find a routing for a 200mm semi-flexible pipe ~500m long from service modules in RR73/77 to the DFH connections to the power converters relocated in the TZ76 gallery Minimum bending radius of 1,5m (to be experienced with multiple bends) Leave free the transport areas in the LHC tunnel and in the TZ76 gallery

  6. Routing inTZ76 SC links Racks Racks Racks Links during installation ? 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 Only one practical solution: under existing cable trays

  7. Routing inTZ76 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 Section along TZ76 and detailed view of the exit UJ76

  8. Routing UJ76 junction – Two options 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 • Tunnel to UJ76 service area: existing ducts are full! • 2 “small” ducts 400mm must be drilled • Between 2m & 3m long, depends on the angle… • UJ76 to TZ76 gallery: 2 main options • without long ducts, along UJ76 bottleneck… • with 2 new long ducts ( ̴19m each)

  9. Routing UJ76 – Option 1 SC Links UJ76 LHC Tunnel 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 2 shorts ducts from LHC tunnel to service area NO new long ducts

  10. Routing UJ76 – Option 1 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 Along UJ76 bottleneck

  11. Routing UJ76 – Option 2 2 shorts ducts from LHC tunnel to service area With 2 new long ducts from UJ76 to the TZ76 gallery

  12. Routing Options – UJ76 Overview of the two options: 1st option (no long ducts) requires more bends and smaller bending radius

  13. Routing R771 towards RR77 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013 3 Sections with various positions of the link & pipe

  14. Routing inside RR77 Connection to cryostat to be studied

  15. Access to Point 7 for SC links Point 6 Point 7 ~3,3 km Point 8 ~3,3 km 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013

  16. Transport of SC links to Point 7 Access Pit PM 85

  17. Access to Point 7 for SC links Access Pit PM 65 Access Pit PM 85 3rd HiLumi LHC-LARP Daresbury SW / JPC 13/11/2013

  18. Transport of SC links to Point 7 500m link ready for handling Space inside PM 85 Surface Building SD8 1,8 5,5

  19. Hard Points • RR73/77 to Long Straight Section (R74 and R771) : • Many constraints due to shielding, metallic structures and supports • need design of the service module • Very few practical solutions in the LHC tunnel and in the TZ76 gallery! • UJ76 crossing: many bends in multiple directions

  20. Conclusions Experience is needed for the transport and installation of two ̴500m long semi-flexible links through curved passages. Thanks to the proposed design, transport and installation of the new DFBs should be a challenge Integration tests will be done at CERN by mid 2015 using a 60 m long cryostat Choice between Option 1 and Option 2 can be made by mid 2015 – and civil engineering during TS in 2016
